OK a couple of things.

My 59 GMC is Canadian and has the same drivetrain as a Chevrolet.

We both believe our trucks to have 3.90:1.

The trucks are 1400 kms apart so I guess we will have to take measurements and pictures to compare.

His diff is making noise and with the tires off the left axle turns freely but the right axle is very stiff to turn.
